CPU (Processor) Support;

1) Intel Pentium 4 processors that have;

A) Use a Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

B) Northwood Core, or Prescott Core

C) Front Side Bus (FSB) of 400MegaHertz (400MHz) for Intel Pentium 4 processors that are based on the Northwood Core.

D) FSB support of either 533MHz, or 800MHz, for Intel Pentium 4 processors based on the Prescott Core.

Processors that have an 800MHz FSB can be used, that have UP TO a 3.6GHz frequency rate. ('Speed')
Indication that higher 'speeds' can be supported. (Overclocking?)

Now let's look at Intel Pentium 4 processors, that are based on the Northwood Core, and fit a Socket 478 processor socket,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Northwood_.28130.C2.A0nm.29

(Front Side Bus = FSB
The M/Ts listing means MegaTransfers per Second.
Believed to be a more accurate method of stating the FSB, than MHz.

MegaHertz
Mega = 1 Million
Hertz stands for Cycles per Second. Was named after a man with the last name Hertz.
Example; 400MHz = 400 Million Cycles per Second )

Intel Pentium 4 processors based on the Prescott Core, and utilizing the Socket 478 processor socket,

sSpec Number will be on the processor, as well as the Part Number.

Scroll down for photos.

CPU support can be attested to looking at the specs for the motherboard chipset, on your motherboard.

The motherboard chipset is an Intel 865PE chipset.
Intel 82865PE northbridge chip, and an Intel ICH5 southbridge chip.

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Pentium_4_chipsets

Scroll down to 865PE in the left column.

The part number on the Intel ICH5 southbridge chip, is Intel 82801EB,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Southbridge_8xx_chipsets

The Northbridge chip of the motherboard chipset, handles the Faster capabilities of a computer.
Processor (CPU), Ram Memory, and HIGH-speed graphics.

HIGH-speed graphics is the AGP technology, or PCI Express technology.

Using a graphics card in a PCI slot, or using Integrated Graphics; is NOT high-speed graphics,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

The Slower capabilities of a computer are handled by the Southbridge chip.

If this is a question of what CPU is on your motherboard at present, and the motherboard is in a working computer, suggest use the free tiny program CPU-Z from CPUID.com,

Need to know how to download, install, and use CPU-Z, post back in a Comment.

The problem isn't so much with your Graphics Card as with your Motherboard. It Supports only PCI x16 1.0 specification, and DDR1. The current standard is PCI x16 2.0 with DDR2 (rapidly moving to DDR3). However, this means that you would need to buy a whole new Motherboard and RAM while still finding a board that can fit your CPU and support it, by that time, you are right, the card is much cheaper to replace (however, a MUCH larger increase in performance will be noticed from replacing the motherboard, RAM, and CPU) I did manage, however, to find an 8400 which fits the PCI 1.0 specification that should work for you : http://www.newegg.com/Product/Product.aspx?Item=N82E16814139035
I hope this helps!

click start run type cmd then type chkdsk/f which will automatically fix any corrupt files on your hard drive then defragment your hard drive
hope this helps

please purchase *********** board cd 

vacuums can cause static electricity. this may have damaged your motherboard in some way. you have to use a special anti-static vacuum when cleaning electronics.

You could ty this site: http://www.driverstock.com/MSI-915P-Neo2-Platinum-driver-download/14-9-11428/index.html to manually owlod the drivers or install MSI LiveUpdate to auto-update MSI software here: http://global.msi.eu/index.php?func=downloadindex

I hope this helps,

Reverse the two-pins connecting the PC Speaker to the motherboard.
This can make any "beep" much louder.

Try a different power-supply, to ensure that your current power-supply is NOT the problem.

Remove the RAM and the video-card, then start it up.
It *should* "beep" to complain about the lack of RAM and the lack of video. If not, and the power-supply is OK, then the motherboard has its own problems.

Go HERE for troubleshooting guide. Scroll down to: Stability Problems - Memory Issues.

The manual shows the correct pin outs, and can be downloaded here:
